Each of these relates to the component being too close to the board edge. The rules are set in the Design Technology, however these are 'warnings' not 'errors' for you to investigate and correct or ignore as required. A connector may have to be placed to the boad edge or beyond so if placed correctly ignore the warning.
If you wish to discuss further post on the DSPCB forum where you will get more advice.
